That's probably a top view looking down on a frictionless table?omka said:Hello
Please why the mass m3 does not fall?
Thank you berkeman for your reply. In the exercice they don't talk about table.berkeman said:That's probably a top view looking down on a frictionless table?
berkeman said:You're welcome. Yeah, if the masses were hanging cantilevered off to the right like that, it would be a pretty weird setup.
If you have any other questions about this problem or other schoolwork problems, be sure to post them in the Homework Help forums, and fill out the Template you are provided there.

Gravity force is the force of attraction between two objects due to their mass. It is one of the four fundamental forces of nature and is responsible for keeping planets in orbit around the sun and objects on Earth from floating off into space.
Gravity force acts on masses and springs by pulling them towards the center of the Earth. It affects all objects with mass, regardless of their size or composition. In the case of springs, gravity force may cause them to stretch or compress, depending on their orientation and the direction of the force.
The greater the mass of an object, the greater the force of gravity acting on it. This means that the force of gravity on a larger, more massive object will be stronger than on a smaller, less massive object. However, the distance between the two objects also plays a role in determining the strength of the force.
The force of gravity between two objects is inversely proportional to the square of the distance between them. This means that as the distance between two objects increases, the force of gravity between them decreases. This relationship is known as the inverse square law.
No, gravity force cannot be cancelled out. It is a fundamental force of nature and is always present between objects with mass. However, other forces, such as electromagnetism, may counteract the effects of gravity force in certain situations.
